试图建立一个数组来存储过去三年存款存入银行账户体系 [英] Trying to setup an array to store the last three deposits into bank account system

问题描述

float deposit (float balance)
{
    float amount[3]; 
    system("cls");
    cout<<"Enter the amount you wish to deposit"<<endl; 
    cin>>amount[3]; 
        balance = balance + amount[3]; 
    writeBalance(balance); 
    return balance;  
}
//This is a function to allow the user to increase their balance 

但是当我在节目中的存款部分输入量的弹出框出现并说：

but when I enter an amount in the deposit section of the program a popup box comes up and says:

Run-Time Check Failure #2 - Stack around the variable 'amount' was corrupted.

任何帮助将是巨大的感谢

any help would be great thanks

推荐答案

您必须输入一个循环数组中的每个元素。更改code以下方式

You must enter each element of the array in a loop. Change the code the following way

float deposit (float balance)
{
    const size_t N = 3; 
    float amount[N]; 
    system("cls");
    cout<<"Enter the amount you wish to deposit"<<endl;

    for ( size_t i = 0; i < N; i++ )
    { 
        cin>>amount[i]; 
        balance = balance + amount[i];
    }

    writeBalance(balance); 
    return balance;  
}

虽然实际上没有必要使用的阵列。你可以在一个常规的变量输入数据。

Though in fact there is no need to use the array. You could enter data in one regular variable.
